I pulled the boys quad out and gettin it ready for the season and I greased the front spindle zerks and I got about 2 pumps in each one before it was full, but on the rear I pumped in 13 pumps and it was still going in pretty easy like there wasnt much grease in there. I was just wondering if there was a specific amount to put in there like a pump or two each ride or every so many months or what.

 

Once or twice a year is plenty.
Careful on the rear as the grease will push out onto the brakes.
Sorry, I do not know how much to put in.
To be honest, I cannot remember putting any grease in mine and they lasted forever.
